Product Usage:

Sodium dichloroisocyanurate is widely used in the sterilization and algae removal of industrial circulating water systems in power plants, petroleum, chemical, textile, electronics, etc., and completely kills the bacteria, such as system pipes, heat exchangers, and cooling towers. Solve the problem of bacterial slime formation and corrosion of pipelines; it is a bleaching and disinfecting fungicide with excellent performance in daily chemical and textile industries; disinfection of water bodies and breeding places in animal husbandry and aquatic products; The fungi and bacteria of the crops are effective; they are cleaned and disinfected in the food and beverage processing industry, and disinfected as swimming pool disinfectants and public places such as hospitals and hotels.


Wool anti-shrinkage treatment agent:

The aqueous solution of sodium dichloroisocyanurate uniformly releases hypochlorous acid, which acts on the protein molecules of the wool scale layer to destroy a part of the bonds in the wool protein molecule, thereby preventing shrinkage. In addition, the treatment of wool products with sodium dichloroisocyanurate solution can also prevent the bonding of the wool during washing, that is, the phenomenon of "pilling". The shrink-treated wool has almost no shrinkage, and the color is bright and the hand feels good. The wool or wool blended fiber and fabric are impregnated with 2%~3% sodium dichloroisocyanurate solution and other additives. , can make wool and its products can not afford the ball, not felting.


Textile industry bleaching:

In the textile industry, sodium dichloroisocyanurate is mainly used as a bleaching agent for natural fibers and synthetic fibers. Bleaching of natural and synthetic fibers destroys the pigments contained in the fibers. Sodium dichloroisocyanurate can produce hypochlorous acid in water. Hypochlorous acid can react with the conjugate bond of the chromophoric group in the fiber to change the wavelength of the fiber to absorb light and destroy the pigment in the fiber. The purpose of bleaching. Compared with traditional bleaching agents, sodium dichloroisocyanurate has many unique advantages. For example, general bleaching agents are required to be used at higher temperatures, and high temperature will aggravate the bleaching agent's erosion of fibers and reduce the strength of fibers. And sodium dichloroisocyanurate can achieve good bleaching effect even at lower temperatures; in addition, bleaching natural and synthetic fibers with sodium dichloroisocyanurate not only has good bleaching effect, but also has low fiber erosion. Moreover, it can also improve the tensile strength and elongation of the fiber, and also remove the cotton pulp, improve the hydrophilicity, and prevent the degradation of the cellulose for the cotton fabric.


Sterilization and disinfection of aquaculture:

1. Sterilization and disinfection of silkworms

Silkworms are very vulnerable to pests and diseases. If the photos are not noticeable, the silkworms are easily deadlocked. Sodium dichloroisocyanurate is a good silkworm, silkworm and silkworm disinfectant, such as sodium dichloroisocyanurate. Or sodium dichloroisocyanurate as the main body, adding a stabilizer and a homogenizer to uniformly mix the disinfectant aqueous solution spray or smoke to disinfect the silkworm, silkworm and silkworm, and prevent silkworm disease. It not only has a good killing effect on the disease of silkworm virus, fungal disease, bacterial disease and protozoa, but also for gastrointestinal type peptic polyhedrosis, gastrointestinal type pus virus, blood type thick disease polyhedron, etc. It has a remarkable killing effect. Compared with the commonly used disinfectant for silkworm, it has a fast dissolution rate, good stability, long potency, no adverse effects on the growth and development of silkworm and silkworm. It is currently developing sericulture. One of Zui's disinfectant drugs.

2. Sterilization and disinfection of aquaculture

Sodium dichloroisocyanurate can effectively prevent fish diseases caused by bacteria, fungi and algae, and has obvious curative effect on fish viral diseases. It can be used in aquaculture such as fish, shrimp, crab, bullfrog and so on. Clear pond, fish species disinfection, water disinfection and fish disinfection.


Civil sanitation:

1. Washing product additives

Sodium dichloroisocyanurate can be used as an additive in household detergents, bleaching detergents, cleaning powders, dishwashing liquids, etc., to bleach and sterilize, and to increase the function of detergents, especially for protein and juice. The cleaning effect is good. When tableware is disinfected, 400~800mg of sodium dichloroisocyanurate is added per 1L of water, and all the E. coli can be killed by soaking and disinfecting for 2 minutes. The killing rate of Bacillus can reach 98% or more after 8min, and the type B can completely kill type B. Hepatitis virus surface antigen, in addition, sodium dichloroisocyanurate can also be used for disinfection of fruits, eggs, disinfection of refrigerator fungicides and disinfection and deodorization of toilets.

2. Swimming pool water disinfection

If the water in the swimming pool is not sterilized, the germs can easily grow. The surface of the pool is covered with a layer of slippery and dirty microbial algae. The pool water emits an unpleasant smell. The swimmers will feel annoyed when they touch the slippery algae. Polluted pool water can also cause swimmers to get infected, light skin infections, severe eyes, respiratory organs are infected. If sodium dichloroisocyanurate is added to the swimming pool water, not only the water is blue, clear and bright, the pool wall is smooth, no The adherent, the swimmer feels comfortable, and is harmless to the human body at the use concentration, and has high sterilization efficiency, which is very beneficial for protecting the health of the people.
